I'm not a doctor, but I play one on TV

Elvis Costello hit it in one:

Sometimes I wish that I could stop you from talking
when I hear the silly things that you say.
I think somebody better put out the big light,
cause I can't stand to see you this way.

When I hear someone express an "Ohmygod! Things in Iraq are going soooo badly" opinion, it seems it's inevitably someone who wouldn't know a hand grenade if she saw one rolling down the street.

Sometimes, I'm annoyed. Sometimes, I'm just embarrassed for them.

Today's "Could you either learn something or just shut up?" comes from -- now don't let this shock you -- the New York Times. Here you go.
